Enseignement
I teach in and am responsible for the masters course called "Advanced Experimental Geomechanics"
I am a CNRS Research Engineer working in Laboratoire 3SR since 2014.
I am an experimentalist and my main research interest is in the mechanics of granular media.
My specialisation is in image-based measurements, and I have co-developed two pieces of open-source software:
I have developed some new ways of extracting data from images, often within collaborations:
In fact I don't think that something can be rightly be considered a scientific measurement without a notion of associated error.
Here are a few studies/tools for metrological studies that I have been involved in:

Software
My specialisation is in image-based measurements, and I have co-developed two pieces of open-source software:
- TomoWarp2: a local digital image correlation code (with E. Tudisco)
- The Software for Practical Analysis of Materials (spam): A large library including discrete analysis and image correlation (with O. Stamati, G. Pinzon, E. Roubin, R. Cailletaud and others). It is available on pip. Since python is named after the "Monty Pythons", we followed suit with the name of this python-based software (sketch here, not for the faint of heart).
Development of measurement techniques
I have developed some new ways of extracting data from images, often within collaborations:
- Quantitative exploitation of greylevel changes during water-induced swelling (with E. Stavropoulou et al.)
- Multi-modal 3D image registration (with S. Roux et al.) and application to concrete (with E. Roubin and S. Roux)
- Single-projection particle positioning of spheres (with B. Marks and S. Roux)
Metrological studies
I am a strong believer in quaniftying the errors that are made with a given measurement tool.In fact I don't think that something can be rightly be considered a scientific measurement without a notion of associated error.
Here are a few studies/tools for metrological studies that I have been involved in:
- Metrology of interparticle contacts from 3D images (with M. Wiebicke, G. Viggiani, I. Herle)
- Analytical tool to make partial-volume spheres in 3D (with A. Tengattini)
- Sphericity measurements from 3D images (with R. Rorato, M. Arroyo, A. Gens)
